A report released Friday by the Arizona Department of Health Services raises questions about whether the program is being abused.
The report says 24 doctors certified almost 75 percent of all cardholders from the inception of Arizona’s medical marijuana program in April 2011 to June 2012.
In all, 475 doctors have certified nearly 29,000 patients.
The report said the most frequently citied reasons for getting a medical pot card was severe and chronic pain.
It also noted the largest per capita share of marijuana patients was in Gila County, followed by Yavapai and Coconino counties.
